this month's topic PumpsGrounded Plastic Pumps Process Flammables
SCP-6500 plastic pumps are capable of handling Class 1 and 2 flammable liquids. All components that contact the fluid are made from conductive plastic so the liquid and the pump, which also has a lug with a grounding wire on its front side, are grounded to the container. These pumps fit containers and drums from 5 gal to 55 gal and are available in four models, each with a lifespan of 10 to 15 yr. They provide for the spill-proof, safe transfer of over 850 fluids and solvents. They are Restriction of Hazardous Substances (RoHS)-compliant and drain containers in accordance with Resource Conservation and Recovery Act (RCRA) emptying guidelines. The pumps are also food-grade and meet UN safety standards.

Progressive Cavity Pump has VFD/Motor Controls
The Moyno metering pump is a progressive cavity pump with integral variable-frequency drive (VFD)/motor controls that improve metering accuracy and repeatability. Its smooth flow is free from pulsations and variations in velocity and volume to prevent material waste and mixture imbalance. It offers precise flow control at low speeds, and handles capacities from 0.1 gal/h to 400 gal/h and pressures up to 300 psi. Its light emitting diode (LED) external displays are easily visible and ergonomically user-friendly. The pump is available in bare-shaft and close-coupled configurations. All models are capable of handling a wide variety of fluids, including: clean, clear liquids; abrasive, corrosive fluids; solids in suspension; and viscous materials.

Pressure-Driven Pump Produces Highly Stable Flow
The Mitos P-pump creates a pulseless liquid flow using a precise pressure-driven pumping mechanism. It is suitable for microfluidic systems such as droplet formation and other applications where highly stable flow is required. The pump operates in a pressure range of 0–10 bar, and has a capacity of 100 µL to 30 mL. It uses fluid directly from the container, producing no mess or waste. Its lockable pressure chamber is easily accessible and accommodates both standard and non-standard fluid vessels.

Plastic Pump Features Onboard Temperature and Vibration Monitor
The NM 3196 is the nonmetallic version of the company’s Model 3196, which is more expensive as it is designed for highly corrosive fluids. The nonmetallic model is made from fiberglass-reinforced plastic and features a high-performance volute design, making its internal casing passageways hydraulically smoother and 20% more efficient than similar metal pumps. The pump features i-FRAME power ends, which incorporate multiple patented technologies to reduce downtime and replacement costs. The i-ALERT component is an onboard condition monitor that automatically tracks temperature and vibration, warning users with a flashing light-emitting diode (LED) display when either condition exceeds normal parameters. The pump’s heavy-duty shafts and bearings provide a 10-yr average lifespan under tough operating conditions. The pump can operate at temperatures up to 195°F and withstand excess vibration up to twice the baseline level. It is available in 13 sizes with capacities up to 1,400 gal/m (318 m3/h) and heads to 500 ft (152 m).

Reinforced Pump Tubing Has a Long Lifecycle
GORE Style 400 high-resilience pump tubing is made from polytetrafluoroethylene (PTFE) and features high-performance Viton filler that allows it to maintain a stable flowrate while pumping aggressive chemicals. This construction makes the pump tubing suitable for nitric and sulfuric acid, as well as aromatic hydrocarbons such as toluene and xylene. The resilient Viton GF-600S is a peroxide-cured fluoro-elastomer based on DuPont’s advanced polymer architecture that provides over 50 times longer life than non-reinforced extruded Viton or Fluorel tubes. Its PTFE reinforcement offers excellent burst resistance to protect against leakage of aggressive fluids. This tubing is available with internal diameters ranging from 1.6 mm to 12.7 mm and wall thicknesses from 1.6 mm to 4.8 mm.
